Abstract

Penelitian ini membahas konflik sengketa perbatasan antara Indonesia dan Timor Leste dari perspektif hukum internasional. Konflik perbatasan antara kedua negara ini menjadi perhatian karena dapat mempengaruhi kedaulatan dan keamanan negara. Penelitian ini menggunakan metode studi kepustakaan dengan mengumpulkan informasi dari berbagai sumber referensi terkait konflik perbatasan dan upaya penyelesaiannya. Pendekatan yang digunakan meliputi pendekatan perundang-undangan, pendekatan kasus, pendekatan sejarah, dan pendekatan fakta. Hasil analisis menunjukkan bahwa  hukum internasional memiliki peran penting dalam menyelesaikan konflik perbatasan ini dan menciptakan ketertiban dan keadilan di masyarakat internasional. Konflik perbatasan antara Indonesia dan Timor Leste dipicu oleh klaim sepihak warga Timor Leste terhadap wilayah Indonesia di perbatasan. Konflik ini melibatkan bentrokan fisik antara warga kedua negara. Penelitian ini memberikan wawasan tentang upaya penanganan konflik perbatasan dari perspektif hukum internasional dan memberikan pemahaman yang lebih baik tentang sengketa perbatasan wilayah Indonesia dan Timor Leste.

Abstract

Wheels are an essential component of a vehicle. Material damage or failure on casting wheel-type wheels is primarily because these wheels receive a reasonably hard impact load due to uneven road conditions or potholes. This condition makes the wheels unable to function normally, and components must be replaced. Given the relatively high cost of replacing wheels, several options are offered to vehicle owners (consumers) to have their wheels reconditioned. This study aims to analyze the effect of the reconditioning process on the mechanical properties and microstructure of the casting wheel material. The sample material is taken from the Original Equipment Manufacturer (OEM) wheel casting wheel in the Disk section for impact testing, Rim for hardness, and microstructure tests. The results are that the reconditioning process affects the mechanical properties and microstructure of the original equipment manufacturer (OEM) alloy wheel material. The decrease in hardness value was 68.86 HBW to 61.59 HBW from the conditions before and after reconditioning. The impact test results where the impact energy absorption is greater after reconditioning is 29.24 J, and the average impact value for wheel specimens after reconditioning is 0.2902 J/mm2. The impact energy value before reconditioning is 7.87 J, and the average impact value is 0.0973 J/mm2. The microstructure obtained is hypereutectic, and the reconditioning process has little effect on the dendritic structure.
